There is a corespondence between states of consciousness and states of matter. Sleep, for instance, coresponds to freezing. So temperature coresponds to thoughts. Lots of decoherent thoughts coresponds to high temperature. When we think, we create electromagentic waves, i.e bosons. Coherent bosons are Bose-Einstein Condensates.
High temperature has something to do with quantum decoherence in that temperature is associated with particles moving to and fro in all manner of directions. This mean that there are all manner of momenti, both in magnitude and direction. This, according to deBroglie hypothesis, mean that there are waves of all manner of wavelengths. Such waves must be decoherent. Coherent waves are those of same wavelengths, hence same momenti. This can only happen at very low temperatures.
In the brain, low temperature coresponds to meditation. This creats coherent Em waves.
